temporarily hide languages ?

Hi there.

I am using your great plugin on my website having 3 languages, all pages duplicated in each language.
It works great, but now I have to do major updates on the content.
So I just want to keep the main language available for user on the website and hide all pages of the 2 remaining languages.
My question, what is the best way to do that ? Is there a special option in the plugin to hide everything from one specific page ?
Thanks for your help.
